IMPROVEMENT m MAGNETIC ENG-INfiS.

The Sjbhedule referred to in these Letters Patent and making part of the same I, HENRY M. PAINE, of city of Newark, and State of New Jersey, have invented certain Improvements in the Construction of Rotary Sector Magnet Engines, 'of which the following is'a specification.

The nature of my invention relates to a peculiar and .novel mechanical arrangement of my sector magnet for purposes of motive force, which has for its object economy of space, cost of construction, and rigidity of parts.

The value of the magijiet attraction being inversely as the square of the distance, it becomes necessary, in order to obtain the best results, to work the poles in as close juxtaposition as possible. To accomplish this requirement, even in very small engines, with the poles working with a between-space of two one-hundredths of an inchwithout cont-act by spring of frame or other parts, requires a heavy cumbrous frame and shaft.

To avoid this'necessity, I so arrange both the rotating and fulcrum magnets that all strain of attraction will be resisted by the longest cross-section of the magnets themselves, and thus just in the ratio that the magnets are enlarged the increased strain is met.

I take any required number of magnet sector limbs A, Figures 1 and 2, and pass the driving-shaft a, figs. 1 and 2, through their several tie-bolt ends I), with Washers c between lto secure even spacing for the current These sector-limbs are then so arranged on the shaft as to make the poles d describe a circle as regards their path of rotation, and a thread of'one or more revolutions as regards 'the length of the shaft. They are then bound in their position by the nuts e 1 and screw-bolts j, which pass through one series of limbs into the next, iill the whole series is securely held in. its required position. I

It will'b seen that this combination presents the longitudinal section of the sector limbs to the strain. The fulcrum magnets B are bound on one common bolt, 0, figs. 1 and 2, in thesame manner that the ro' tating magnets A are held, and their poles h are bound by the rodst' passing through the whole series, which make one uniform breast of sector limbs, the axis of all lying in one common plane.

As in the rotating magnets, so in these, all the strain is met and resisted by the longitudinal section of the limbs, and this extreme st-ifi'ness of construction allows the two series of magnets to be brought in close and accurate range of motion by means of .the
